Q.
In $SiO_{4}^{4-}$ , the tetrahedral molecule, two oxygen atoms are shared in
The p-Block Elements
Solution:
In sheet silicates, three oxygen atoms of each tetrahedra are shared with adjacent $SiO_{4}^{4-}$ tetrahedra. In chain silicates, two oxygen atoms are shared by each tetrahedra.
Double-chain silicates occur when tetrahedra form a double chain by sharing two or three oxygen atoms. In $3D$ silicates, each tetrahedra shares all the four oxygen atoms with its neighbours.
